A Double Diatom Under an Amscope Microscope Found this double Diatom, which may be about ready to split into two individuals. I used an Amscope and Tucsen 10Mp video camera to get these shots. I used Movie Edit Pro 16 to combine 5 short AVI's and convert to mpg2 for upload.

Diatom Asterionella formosa. Microbiology in England Freshwater plankton Desmidia Wide version Asterionella formosa A species of spring, summer and fall blooms in lake phytoplankton. Known to have one of the slowest sinking rates of freshwater phytoplankton. Projects exist that use lakes and slow flowing "ponds" as model systems to observe UV damage & the effectiveness of different molecular mechanisms of UV defense in phytoplankton, bacteria, protozoa, zooplankton & fish. This is singularly my most favourite freshwater organism. Its difficult for me to find in England. And exceptionally fragile and getting 4 together seems to be very chance. I have noticed a slight increase in this lifeform in the last8 years but sadly Chlosterium seems to have completely dissapepared from my local waters. As soon as I find out something about this I shall include it herewith. until then I am at the mercy of the professionals. Microbiology in England Freshwater plankton Desmidia Wide version

Brownian Motion inside Diatom 1000x The Diatom and surrounding Cyanobacteria were from Heron's Head Park Salt Marsh, San Francisco Bay. Magnification was 1000x under Hoffman Modulation Contrast optics. Camera was a Nikon Coolpix 885 at 3x zoom. The particles inside the Diatom exhibit Brownian Motion [see "Brownian Motion" Wikipedia for details]. It is not clear what the particles may have been. I doubt they were bacteria. It is more likely that each particle was either a mycelle or a vesicle [see Wikipedia for both terms]. Life is, indeed, wondrous to behold. What "miracle" could compare with this very common biological and physical event? [see Wikipedia for "miracle".]

The diatom Story - Use Nualgi for a Clean and Green Environment part1 This is a documentary about Nualgi, a research product. Nulagi has been used to clean lakes, prevent mass fish kill, provide a good sustainable environment for fishes to live and help in preventing Global Warming. Nualgi helps to grow algae which can be used to extract bio fuel. Growth of Algae absorbs Carbon dioxide from atmosphere and thus helps to prevent Global warming. For more details visit

Computer Simulations of Diatom Morphogenesis Computer simulations of a stage of diatom morphogenesis. In the video there are real and simulated images of some diatom species. In the simulated images, the dark parts correspond to organic-rich regions which eventually can act as templates for the subsequent deposition of silica. The physico-chemical model adopted in the simulations is based on a phase-separation mechanism. For more info follow the link to the relevant scientific publication

Nano Lagoon (14): BIG Diatom Bloom Just ten days after adding the NanoStart microorganism kit to our lifeless Nano Lagoon marine aquarium we observe a classic diatom bloom on the rocks and sand. The tank now has a developing population of beneficial microorganisms. These include bacteria, protozoans, diatoms, microphytoplankton and microzooplankton. The NanoStart kit comes with these components, plus nutrients and a Coralline Algae Booster Plate which we've placed into the hang-on filter box. We want the succession of life forms in our Nano Lagoon to mimic that which occurs on bare substrates on natural coral reefs. So far we are on schedule with the diatom bloom, which normally occurs within about two weeks of adding the first marine microorganisms. Note that by using dry rock and sand plus a microorganism startup kit we have eliminated the tedious rock curing, the mass invertebrate die off and the toxic ammonia spike normally associated with wild live rock. We have done no seawater changes since starting the tank with Instant Ocean sea salt. Using dry, man-made rock saves time, labor and money. It makes great environmental sense because it does not require harvesting wild rock and air freighting it halfway around the world while most of the associated organisms die in transit. Our 40-watt light unit was late to arrive for this demonstration, so for the 10-day startup period we relied on indirect natural lighting to grow our diatoms. At home you would use 40 watts of PC lighting, with 50 ...

Diatoms Moving In A Tube These small pennate Diatoms formed an extensive mat of "sheath-like" Tubes on the bottom of a salt marsh pond in Heron's Head Park salt marsh, near study site OS-1. In most of the Tubes the Diatoms were packed, but the sparse population of Diatoms in this Tube made possible videomicrography of the Diatoms moving slowly along the Tube. Microscopy was with Hoffman Modulation Contrast optics at 1000x magnification, oil immersion. The videomicrograph was taken with a Nikon Coolpix P5100 attached to a threaded Leitz Wetzlar 10x eyepiece. How the Diatoms form the Sheath Tubes is not known.

Diatom algae control by Sally Jo. This video will show you how to control Diatom algae in your reef aquarium. At we use a mix of reef janitors to control diatom algae and red slime Cyanobacteria in our reef aquariums. Cerith snails and red leg hermit crabs can clean your reef aquarium in a few days, and they will keep it clean.

Big Golden Pennate Diatom Rolls Along This big [about 0.2-mm long] golden diatom was in a sample from a Heron's Head Park Salt Marsh Pond, San Francisco Bay. Shots were taken with a Swift FM-31 Field Microscope at 400X using a Nikon Coolpix 885 Digital Camera. Diatoms are algae in a glass case - the two shells that enclose a diatom are made of silicon. Algae are plants, so Diatoms get their energy and manufacture sugars from the sunlight and CO2. They also frequently move with a slow, but steady motion. Diatoms evolved at about the same time as mammals, so they are relative newcomers.

Nano Lagoon (15): Poof! No Diatoms Just five days after introducing a Nano Lagoon Cleanup Crew to our 10-gallon Nano Lagoon reef tank, the organisms have done a great job of cleaning the rocks and sand of the diatoms present on Day 10. The Nano Lagoon Cleanup Crew contains captive-bred Reef Amphipods, ReefWorms, MiniStars and several types of algae-grazing snails. We now have the beginnings of a dynamic food web developing amongst the microorganisms and herbivorous invertebrates in our Nano Lagoon. It has taken only about two weeks since starting with dry sand, dry man-made rock and Instant Ocean. Now, populations of bacteria, protozoans, microalgae, reef plankton, 'pods, worms, snails and MiniStars are adjusting their densities in accordance with the food, space, nutrients and other organisms present in the tank. An ecosystem has been born! No water changes have been done since we started the tank. Please use only captive-bred organisms in your reef aquarium.

Diatoms in aquaculture Diatoms are the best food for Fish and Shrimp. Nualgi causes a good bloom of Diatoms. Diatoms also give huge amounts of oxygen and keep out blue green algae. Most Diatoms are brown and turn the pond brown.

Spirochaetae and Diatoms Lead a Busy Life This film was made using a Swift FM-31 Field Microscope and Sony DSC-W7 Cybershot Camera, viewing a sample taken from a San Francisco Bay Salt Marsh pond at 800X magnification. The "snake-like" critters are Spirochete bacteria and the "boat-shaped" ones are Pennate Diatoms. Diatoms are algae in glass [silica] shells. That means they are tiny photosynthetic plants, using sunlight for energy. The role of the Spirochetes in this pond community is not known. Of the many millions of species of bacteria, only a very few are pathogens and even fewer are human pathogens. These little guys probably make their living digesting the remains of plant and animal material in the pond. The water in salt marsh ponds is often very salty, being as much as 5% salt.

The Important Little Life of Dylan Diatom Watch this 3D animation of Dylan, a centric diatom in the Arctic Ocean. A floating plant at the bottom of the food chain, Dylan's hunted by copepods, terrorized by the elements, plagued by a warming Arctic, but triumphs in this slice of life. Sponsored by the National Science Foundation, "The Important Little Life of Dylan Diatom" is designed for middle school students to witness the role of phytoplankton in the Arctic and the effects of warming.

Diatoms in darkfield This is a sample of a single drop of river water. The majority of the creatures you can see are diatoms; beautiful single-celled organisms encased in a frustule, a porous external layer composed almost purely of silica. The magnification here is between 40X and 200X. The shimmering effect is due to the video sensor struggling with the low level of light. In reality, the diatoms appear pin-sharp and full of colour against the pitch black background

Learn about Diatoms ...with Poetry! Diatoms, are an algae group, dia in Greek means to cut through, they've been around before me and you, and prove that the smallest can survive too! Look real close, and you will behold, new worlds inside a microscope. This story begins within the oceans, where resides a type of phytoplankton. Diatoms, they are a small algae, whose little lives are quite astounding. And it's ok if you don't get it yet, the words that we use are a bit complex. These organisms are very, very small, and are surrounded by a silica wall. The cell itself consists of two halves, while the wall holds ribs, pores, even a back! Diatoms two types, the first Pennates, just think pen; they have a thin-shape. The other is Centric, circular centers, Centric, circular, now you remember! Diatoms, are an algae group, dia in greek means to cut through, they've been around before me and you, and prove that the smallest can survive too! Since the Jurassic they've been around, in numerous fossils many were found. As evidence when extinction dawned, they diversified, evolved and held on. Sticking together, they form a colony, today they help measure water quality. Keeping the balance they remain, critical producers in the food chain. Tiny, small, bifurcation, unicellular, most basic. Algae, phytoplankton, cell, colonies, a place to dwell. Home is oceans, water, Earth is, best when wet so they can flourish. Diatoms, they are a small algae, whose little lives are quite astounding.

Diatom On Amscope Microscope and tucsen 10Mp Video Camera Yesterday, after a tip on how and where to collect subjects for the microscope, I went to a pet shop and bought a nice dip net with a 3 foot stainless handle and a super fine mesh net. This morning, I drove down to the Mississippi River in town, near a boat ramp, and collected some duckweed and some other water plants, by scraping the edge of the net bail along the plants and bringing up some pieces, along with the bugs that were attached to them. I also added some water from the river. I was able to collect some great specimens, some weed and some bugs actually big enough to see. This is two videos taken with the Tucsen 10Mp video camera in one of the eyepieces of the Amscope microscope and then merged together and a music track added in Movie Edit Pro 16. The Amscope is a trinocular microscope, but did not come with the proper adapter for the third tube so I could mount the Tucsen camera on it. The camera does mount, but the adapter is way too long, and the image quality suffers greatly. Using the camera in the eyetube gives much nicer video quality.

Beautiful Diatoms Cycling a new sal***er aquarium begins with two basic steps, the bacterial bloom and the diatom bloom. Living bacteria and diatoms must be introduced to the tank along with a nutrient source before these processes will occur. Rock and sand substrate should be in place in the main display tank before the cycling begins. Circulation pumps and powerheads should be on and lights should be running on a normal 12-hours-on, 12-hours-off cycle. No skimming is required during cycling. The bacterial bloom occurs first and makes the seawater slightly cloudy. The diatom bloom occurs next and leaves faint brown streaks on the rock, glass and sand. These processes may take 2-3 weeks to run their course. No water changes are needed during this period as they will only prolong the cycle. Diatoms are microscopic, single-celled algae with siliceous shells (made of silica). They are ubiquitous in the marine environment and along with bacteria are early colonizers of barren substrates like lava flows, dead coral, shipwrecks and artificial reefs. Many organisms consume diatoms in nature including single-celled protozoans, sponges, corals, gastropod and bivalve molluscs, crustaceans, echinoderms, fishes and marine mammals like whales. Diatoms reproduce a***ually by simple cell division (mitosis). They may also reproduce ***ually after many mitotic divisions, or even enter a resting stage. They exist near the very base of the marine food chain and help support complex food webs ...
